Gridface Princess is a character who makes a very short cameo in "What is Life?" in Ice King's Imagination Zone. She also appears in "Loyalty to the King" and "Princess Potluck." Her first speaking role was in "Something Big." According to the events in "Princess Day," she is a registered princess.
Not much is yet known about Gridface Princess's personality. However, it is implied that she has at least some skill and interest in technology, given she provided the force-field used to temporarily contain Darren.
She wears an orange suit that completely covers her body. There are parts that have orange/burnt orange checkers on her boots, gloves, neck, waist, and face.
